The National Commodity and Derivatives Exchange (NCDEX) launched RAINCHNNAI, a weather futures contract linked to Chennai’s Northeast monsoon rainfall.
The contract is cash-settled and uses official India Meteorological Department (IMD) rainfall data from Meenambakkam and Nungambakkam stations.
Chennai receives nearly 70% of its annual rainfall from the Northeast monsoon, mainly during October–December.
RAINCHNNAI uses the Cumulative Deviation Rainfall (CDR) model to measure rainfall deviation from the Long Period Average (LPA).
The contract initially has expiries in September, October, November and December.
It is designed to help sectors such as agriculture, logistics, retail and utilities manage financial risks caused by rainfall variations.
